Limit on MixRGB nodes per material? Or How to render out an image sequence
Okay, so the original challenge was to create a material that would change every frame, so that I would end up with 33 images that would have a different art piece on the wall.
First, I tried using a mixRGB shader animated to switch between images. But, I got stymied by a memory problem. Blender would only see the first 8 images before it seemed to lose its mind.
Then, on a recommendation from @no-can-do , I switched the image texture node from single to image sequence.
This seemed to work until I rendered, then it would lose the images again.
I upgraded from 2.82a to 2.83, and rendered again. And, it worked!
Image sequence is set up with the number of frames (number of images in the directory I was linking to), start frame of 1 with 0 offset. I also clicked the Auto Refresh on.
Here's my set up:
